I had to think a lot because that’s a big change (technically simple I
think, but it’s the change of UI and habits that’s bigger ;-)).  I came
to the conclusion that it’s probably a necessary thing.

Regarding the aesthetics, I’d be in favor of using @ for the version:

  guile <at> 1.8
  guile <at> 1.8:doc

I’m not sure if we should also allow:

  guile:doc <at> 1.8

Thoughts?
